INGREDIENTS YOU NEED

How to make spinach quiche in a pressure cooker
This simple recipe works in any brand of electric pressure cooker, including the Instant Pot, Ninja Foodi, or Power Pressure Cooker XL.
To begin, place a trivet in the bottom of your pressure cooker. Add 1½ cups of water.

To prepare the quiche batter, whisk together the eggs, milk, salt and pepper. Place the chopped baby spinach, diced tomato and sliced green onion in a 1 ½ liter baking dish and mix well.
Pour the beaten egg mixture over the vegetables in the baking dish and stir. Carefully place the sliced tomatoes on top and sprinkle with a layer of Parmesan cheese.

Use a sling to lower the bowl onto the mat in the pressure cooker. Lock the lid in place and cook on high pressure for 20 minutes. When the cooking time is up, turn off the pressure cooker and allow the pressure to release naturally for 10 minutes, then finish with a quick pressure release.
When the valve drops, carefully remove the lid and use the sling to remove the bowl from the pot. If you like, bake the quiche in the oven until it gets a little colour.

Important Tips for Making Instant Pot Quiche
Since this is a crustless quiche, the texture and flavor of the egg mixture are very important. Don’t be afraid to season the eggs well with salt and pepper. And make sure you whisk the eggs and milk thoroughly before pouring the mixture over the vegetables, or your quiche may not bake evenly.
It is also important to grease your baking dish or cake tin well before adding the vegetables. This ensures that the tomato pie will be easy to remove and serve.

Products
There are a few handy products to make this Instant Pot quiche. First you need a coaster. Most Instant Pot models come with one, but if yours didn’t, we love this one coaster.
You’ll also need a 7-inch round cake pan. This pan from Fat Daddio’s fits in a 6-quart pressure cooker. You can also use a 1½ liter soufflé dish. Just make sure it’s oven safe!
To lower the quiche into the pressure cooker and remove it, you need a carrier. You can make your own harness from aluminum foil. Or invest in this fantastic OXO reusable harness if you log pot-in-pot cooking in the Instant Pot.

Frequently asked questions about making spinach quiche
yes! This is a great petition right. Simply wrap it tightly in plastic wrap or store in an airtight container, then refrigerate until ready to serve. You can serve the quiche cold or heat it in the Instant Pot to serve.
Yes, freeze leftovers in an airtight container for up to six months. Thaw in the fridge overnight before serving.
You can replace the spinach in this recipe with another green, such as kale or chopped kale. Or try sliced, sautéed mushrooms, diced sweet onions or peppers instead of tomato.
Sure! For best results, use a shredded or crumbled cheese to replace the Parmesan. Cheddar, Swiss, blue or goat cheese would all work great.

Notes
I cooked it without foil covering the top. There was some liquid on top of the pie after cooking, but I just use the corner of a paper towel to soak up the liquid. If you prefer to cook it with foil on top, you must add at least 5 minutes to the cooking time and test if it is done.
